How to change the power supply to the CD/DVD Drive so that it is off by default?

When running on battery I often use the "Safely Remove Hardware" icon from XP to "unplug" the Mat****a CD/DVD drive in order to safe some battery life.(Does it?) I use Fn+Tab to bring it back to life. I wonder if there is a way to make my Notebook (M400) boot with the power supply to the Drive off by default. By the way, any idea where I can find the extra battery for the CD/DVD-Drive slot and at which price?
Thanks in advance for your help.

Hello Robert
If you check start page you will see that this support forum is not any kind of Toshiba support directly but user-to-user forum. But you are not alone and many users expect that some Toshiba support team sit in the office and wait to write answers.
Anyway there are many Toshiba notebook users with very good knowledge and also enthusiasts who try to help other guys with different issues and also share own experience.
Professionalism is not forum but action when you need assistance because of hardware damage or something similar. If you need competent answers and help every authorized service partner should be able to give you info you need. But please dont mix service partner and Toshiba because it is not the same.
Anyway I have found info that you can use additional (second expansion battery) and it should be batteries with part numbers PA3510U-1BAL and PA3510U-1BRL. I can not tell you how much it costs but you can find it alone using Google.
Back to your first question: If I am understand you right you want to save more power and because of that you want to disconnect ODD. It is nice idea but you have obviously misunderstood something. "Safely Remove Hardware option is there to help operating system and say this hardware part will be removed and dont exist anymore but it does not mean physically disconnection from other hardware.
If you need more power use second battery and enjoy your life.
If you have more questions you are welcome. Many users here have M400 and I hope in the future some of them will participate a little bit more.
Have a nice day! :)

How to check the power supply? iMac G3 233

How to do it?
Can i just take the case with the mainboard out and "short" the pins Power on (pin 8) with GND and check the voltages on the connector that comes out of the monitor case?
I know that the pin 8 is the power from articles about imac>atx case conversion.And i know that you can power up a normal ATX power supply by shortening two pins, and want to know if i can do the same with iMAc power supply. I don't want to fry anything.

Sounds like you have eliminated most of the possibilities, other than power supply board or motherboard. But it may also be the CPU daughter card that is faulty. I had one (233 MHz) that would run Mac OS 9 just fine, but it was unable to run Mac OS X reliably (crashes and freezes after a few minutes). I replaced it first with a 333 MHz G3 card off of eBay and later with a 467 MHz G4 card from the Fastmac booth at MacWorld San Francisco two years ago.
If you are comfortable disassembling the iMac to the point of removing the power supply board, you can layout the PS board and the carrier assembly (the thing you pull out with the motherboard, CPU card, and drives) on a table top. Then connect the power supply board to the carrier assembly, and connect the external power cord plug to the power supply board, and connect a keyboard with a power button to the carrier.
To measure the voltages, you can disconnect the 4-pin connector to the hard drive. If you turn it on using the power button on the keyboard, it will not start up with the hard drive not powered up (unless you use a bootable CD), but the system should be powered so that you can take your measurements.
Hope that works. Be careful with the exposed back end of the CRT. Keep any curious cats out of the room while you do this...

How can I replace the power supply IN the time capsule

I have a TimeCapsule that has a bad powersupply. I have opened the timecapsule to confirm this. Has anyone done this before? If so, where did the power supply come from? Cost? I took this to the Apple Igneous bar and they said there is nothing that can be done about it.They said it couldn't even be opened, but simply peeling the rubber bottom off and unscrewing a number of tiny screws and that's it. The 1 TB drive is LOOSE in there. That was a bit of a surprise. I had thought that the issue was the drive itself was bad. I had hoped that if I removed that the AP part would at least work, but after opening it up and firing it up I could hear that the power supply was buzzing thus the conclusion it was the issue.
I am going to put the SATA drive in a reader to see that it is indeed ok. If that checks out, then I know for certain it is the power supply, but I don't know what to use as a sub since the unit needs both 12V and 5V. I'd just as soon find a good supply and use that. Any help would be appreciated.
Thanks,
John A Kostelac

What version is your TC.. A1xxx from the rubber foot?
Power supplies are not available from apple. They do not consider it repairable. It is a sealed consumable.
Power supplies are available from ebay.. simply type time capsule power supply into search.
This is absolutely standard issue that has been ongoing for ages and ages.
See https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair
For a multitude of ways to fix it.
The 1 TB drive is LOOSE in there.
No, it is not loose, it has rubber mounts with pins in the bottom base plate. You cannot see the mount points with the base off. This is standard hdd mount for low noise and vibration.
I had thought that the issue was the drive itself was bad.
Drives seldom are the problem. The Gen2 WD black has been less than great though.. and later spinpoint in Gen3 not so good.

How do I know if the Power Supply is shot?

Hi, I have G5 with a dual processor, purchased in 2003. I recently bought a new iMac and wanted to give the old G5 to a family member. The G5 just went dead, I think it took it personally.... I have done the resetting of the PMU, I have replaced the lithium battery. Nothing. Is there any way to test the other things to know what's dead? Is the power supply the next logical culprit? I know this computer isn't worth much but I'd like to have it limp along for another year. Any hints or ideas would be appreciated. I have been a huge fan of Discussions but this is my first post. Thank you.

Many moons ago, my previously trouble-free Mac IISI died less than a week after my Power Mac 7600 arrived. Spooky, ain't it?
Hope you were able to resuscitate your G5.

I had an Intel-iMac fried by lightening. UPS, surge protectors but it happened as I was reaching to unplug. Cold now. Could it just be the power supply? Can I replace that myself?

This is the full question since I couldn't get it all in the box.
I have some complex questions regarding an iMac, a Time-Machine backup, and iTunes on an iPod.
I live about halfway up an extinct volcano about 12 miles north of San Jose Costa Rica. Some months ago, we had a thunderstorm and as I reached to unplug my computers lightening struck about 50 meters from my house. I had an iMac with a 3-Tb external backup drive, a PC laptop and a laser printer on the same power strip. There was a definite surge and the light brighten and then power was lost for a few minutes.
When power was restored, the PC and the laser printer seemed to work fine but the iMac was cold.
First questions: Is is possible that the power supply was fried and not other essential parts? Would it be worthwhile to replace the power supply? Can I, with limited experience and tools do it or need I take it to a technician? My concern is that if the hard-drive is good, there is personal information on it that I don't want to risk.
Next question: Do I need to replace the hard-drive before taking it for service? How hard is that, can I do it? I have seen videos of the drive replacement on-line.
Those are my iMac questions, now the questions about backup restoration.
If there is a saving grace with this it is that the Time-Machine backup seems fine although I have only accessed the data through Finder. I replaced the iMac with a Macbook Air with significantly less mass storage and I can't just move files to the Macbook. My problem is that I have an iTunes library of some 10,000 songs on the backup and until recently on a 160 Gb iPod which was old and it crashed. I have replaced the iPod but have not tried to restore the iTunes library to it because of my confusion about how to do that. Can anyone tell me how I might do that or give me any insight into the process?
Thanks for any help you can give.

Quite possible, but working on iMacs is not easy, & PSU might be prohibitive.
Hopefully the Drive might have info on it, but even pulling that out can be a chore.

I'd get an external drive & restore the whole works to it, then boot from the External drive.

Can I keep plugging in my iphone to the power supply despite fully charged to reduce the battery cycle?

Since an iphone battery lasts for 300-500 cycles before losing its juice, can I just continuously connect my iphone to the power supply to avoid using the battery, like how I use my macbook.

Yes, you can but best read this

Apple Keybord ADB (Anyone knows how to use the power button?)

Hi, I just found my uncle's old Mac SE and I was wondering if anyone knows how to set the power button on the keyboard (Apple Keyboard) model number M0116C? I want this key to work, because it is actualy not working.
Tanks!

You don't make any settings for the power switch; either the Mac can use it or it can't. The Mac SE has a rocker power switch on the back of the CPU. The keyboard can't change the state of the power supply. Later Macs could, but not the SE.

Use SNMP to monitor the power supply status of stacked switches

Does anybody know how to use SNMP to monitor the status of the internal power supplies of a group of stacked Cisco 3750 switches?
The switch stack has three 3750-48PS-E switches inter-connected by Cisco StackWise cable. IOS ver 12.1(19)EAlc. A single IP address is used to identify the switch stack. Every time I poll the OID chassisPs1Status (1.3.6.1.4.1.9.5.1.2.4.0 in CISCO-STACK-MIB), I only got the status for the Master switch of the switch stack. Is there any way to poll the power supply status of other switches in the switch stack?
Thanks a lot!

Sorry to refresh such an old topic - but I am stuck with exactly this: Monitoring power supplies of a stacked Cisco Catalyst 3750-E.
I'm using the exact same OID's as described, but the problem is, the information shown on the SNMP output is not correct.
This morning, a power supply of the first switch failed and switched to RPS. Here the information I got on SNMP:
snmpwalk -v 2c -c public 192.168.1.50 1.3.6.1.4.1.9.9.13.1

SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.2060 = INTEGER: 2
As you see, both PS1 (for both switches) are appearing normal. It doesn't even recognize RPS:
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1059 = STRING: "Sw1, PS1 Normal, RPS NotExist"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2060 = STRING: "Sw2, PS1 Normal, RPS NotExist"
The first switch's power supply died and now the cable is disconnected. LED's of the power supply are out. And still: The switch happily announces by SNMP it's power supplies are up.
Is this a known bug? If yes, has it been fixed?

I just replaced the power supply in my Intel imac and now the screen is really really dark and I see the missing folder icon, what do I do?

The power supply in my Intel iMac went out (and smelled pretty burned) so I replced it and now when I start it up the display is so dark I can hardly see it and it shows the missing folder icon. Is it the inverter? Or if shine a flashlight on it and re-install the OS will changing the display settings maybe fix it?

Thanks for ur quick reply to my problem. I tried all of that with no results... I did notice tho that the lights next to and above my caps lock key and my num lk key are now flashing. They flash in unison three times then there is a two second pause then they flash three more times and this repeats. They may have been doing this before I tried this solution but I did not take notice until now... I was also wondering how I am supposed to know, after pressing f10 to enter bios, how I can tell if my new drive is being detected when my monitor will not function? Was pressing f10 supposed to possibly make the monitor turn on? In a last ditch effort to try and further identify the problem, I re installed my old drive. Before replacing it my computer would begin to boot then display a hard error that would not allow me to continue booting and run Windows. My display would still work but I could not run Windows. After re installing the drive the monitor will not turn on. I'm beginning to think that I have a bad monitor. Is there a way of testing this with out buying one? Where does the monitor connect to the mother board? I wonder if maybe its been jarred loose, although I highly doubt it, it may still be worth looking at. Thanks again for your advice.

My unit went down hill fast from trying to boot up to only the power supply fan runs.

The power on lite is on. The DVD lite flashes then stops. The card reader lite is on. Is this the end of days for this piece of junk!!

ditwad,
I've also responded to your other post about support, and asked there for some of your specifics - contact info, system model type and serial on bottom of the unit, and your last case number. If you could send me those in a private message (little envelope in the forum), I'll try to arrange some further help.
By your post title, I get the broad strokes of the matter - it's gone from bad to worse.   In order to get more valuable help from other's in the forum, it is helpful to provide some details.
What model desktop system do you have?    What has been happening that led up to these recent events? Was anything changed or added to the system?
No video? No beeps?    You note the power supply / fan spins. How about the hard disk, can you hear it spin up?
Best regards,
Mark

How to control HV power supply (0-5V control voltage)?

Hey there,
I (LV newbie) wonder how to control my DELTA ELEKTRONIKA Powersupply with Labview. The control interface is a 0-5V analog input to set the power supply's output current.
Also I want to get some feedback of the set power supply current from an second (GPIB-controlled) instrument.
So how do I have to program a closed loop contol (application is not time critical), cause it would be mixed up of controlling by analog out (0-5V) and feedback loop driven on the GPIB-Card?
For a first step a simple control loop to set the current and monitor it on an analog input would also be an assistance .
THX for anyone helping

Look in the example finder for DAQmx functions for analog input and analog output.

HT2811 If the display flashed short long short could the power supply be bad?

If the display flashed short long short could the power supply be bad?

Hello,
In order to determine what might be going on, I am going to need a little more information about your setup such as:
-what version of the cFP drivers are you using?
-where/what device are you outputting voltage to? at what voltage? how much current do those devices require?
-could you explain further by what is meant by '[at] approximately 30 seconds, all channels on that PWM shut off'. Are the lights on the modules still illuminated when the system 'shuts off' or do they remain on?
-Do you have another power supply you could try this with?
-Does the power supply meet the specifications for use with this module per p. 4 and 5 of the FIELDPOINT AND SPECIFICATIONS™ OPERATING INSTRUCTIONS FP-PWM-520 and cFP-PWM-520 Eight-Channel, 5 V...
-Does the power supply continue to output 24VDC even after the 'shut down'?

Display the power supply status in the IPS 4270

How to display the status of the power supply on the IPS 4270
since the IPS has two power supplies and one has failed, so i want to check what is causing this failure (i am looking for a message from the CLI describing that the IPS power were failed).

At this time, there is no method to display the status of the power supply from the CLI or IDM GUI of the IPS-4270. There is an open enhancement request to have this capability added in a future release of the IPS software.
